spring整合hibernate 有两种方式 1、注解方式 2、xml方式实现
Spring整合Hibernate有什么好处？
1、由IOC容器来管理Hibernate的SessionFactory
2、让Hibernate使用上Spring的声明式事务
1.xml方式：
大概架构：
我们将会创建一个账户类，实现添加的功能
首先先添加Spring 和 HIbernate的jar包节点：
1 <dependencies> 2 <dependency> 3 <groupId>junit</groupId> 4 <artifactId>junit</artifactId> 5 <version>4.3</version> 6 <scope>test</scope> 7 </dependency> 8 9 <!--jta的jar包--> 10 <dependency> 11 <groupId>javax.transaction</groupId> 12 <artifactId>jta</artifactId> 13 <version>1.1</version> 14 </dependency> 15 16 <!--mysql数据库驱动--> 17 <dependency> 18 <groupId>org.wisdom-framework</groupId> 19 <artifactId>mysql-connector-java</artifactId> 20 <version>5.1.34_1</version> 21 </dependency> 22 23 <dependency> 24 <groupId>org.hibernate</groupId> 25 <artifactId>hibernate-core</artifactId> 26 <version>5.0.6.Final</version> 27 </dependency> 28 29 <!--以上是HIbernate的jar包配置--> 30 31 <!--下面是Spring相关的jar包配置--> 32 <!--c3p0--> 33 <dependency> 34 <groupId>com.mchange</groupId> 35 <artifactId>c3p0</artifactId> 36 <version>0.9.5.2</version> 37 </dependency> 38 39 <!--AOP的相关jar--> 40 <dependency> 41 <groupId> org.aspectj</groupId > 42 <artifactId> aspectjweaver</artifactId > 43 <version> 1.8.7</version > 44 </dependency> 45 46 <dependency> 47 <groupId>org.springframework</groupId> 48 <artifactId>spring-context</artifactId> 49 <version>4.2.0.RELEASE</version> 50 </dependency> 51 52 <!--Spring-ORM--> 53 <dependency> 54 <groupId>org.springframework</groupId> 55 <artifactId>spring-orm</artifactId> 56 <version> 4.2.2.RELEASE</version> 57 </dependency> 58 59 </dependencies>
Stock(账户类)：
1 package cn.happy.beans; 2 3 /** 4 * 股票类 5 * Created by CKW on 2017/4/2. 6 */ 7 public class Stock { 8 private Integer sid;//编号 9 private String sname;//名称 10 private Integer scount;//余额股 11 12 public Stock(String sname, Integer scount) { 13 this.sname = sname; 14 this.scount = scount; 15 } 16 17 public Integer getSid() { 18 return sid; 19 } 20 21 public void setSid(Integer sid) { 22 this.sid = sid; 23 } 24 25 public String getSname() { 26 return sname; 27 } 28 29 public void setSname(String sname) { 30 this.sname = sname; 31 } 32 33 public Integer getScount() { 34 return scount; 35 } 36 37 public void setScount(Integer scount) { 38 this.scount = scount; 39 } 40 }
dao层接口(StockDao)：
1 package cn.happy.dao; 2 3 4 import cn.happy.beans.Stock; 5 6 /** 7 * Created by CKW on 2017/4/2. 8 */ 9 public interface StockDao { 10 //添加 11 public int addStock(Stock stock); 12 }
dao层实现类(StockDaoImpl)：
1 package cn.happy.dao.impl; 2 3 4 import cn.happy.beans.Stock; 5 import cn.happy.dao.StockDao; 6 import org.hibernate.Session; 7 import org.hibernate.SessionFactory; 8 9 import java.io.Serializable; 10 11 /** 12 * Created by CKW on 2017/4/2. 13 */ 14 15 public class StockDaoImpl implements StockDao { 16 17 //植入一个工厂对象 18 private SessionFactory sessionFactory; 19 20 public int addStock(Stock stock) { 21 Session session = sessionFactory.getCurrentSession(); 22 Serializable count = session.save(stock); 23 return (Integer)count; 24 } 25 26 public SessionFactory getSessionFactory() { 27 return sessionFactory; 28 } 29 30 public void setSessionFactory(SessionFactory sessionFactory) { 31 this.sessionFactory = sessionFactory; 32 } 33 }
service层接口(AccountService)：
1 package cn.happy.service; 2 3 4 import cn.happy.beans.Stock; 5 6 /** 7 * Created by CKW on 2017/4/2. 8 */ 9 public interface AccountService { 10 11 //添加 12 public int addStock(Stock stock); 13 14 }
service层实现类()：
1 package cn.happy.service.impl; 2 3 4 5 import cn.happy.beans.Stock; 6 import cn.happy.dao.StockDao; 7 import cn.happy.service.AccountService; 8 9 import org.springframework.transaction.annotation.Transactional; 10 11 /** 12 * Created by CKW on 2017/4/2. 13 */ 14 public class AccountServiceImpl implements AccountService { 15 private StockDao stockDao; 16 17 @Transactional 18 public int addStock(Stock stock) { 19 return stockDao.addStock(stock); 20 } 21 22 public StockDao getStockDao() { 23 return stockDao; 24 } 25 26 public void setStockDao(StockDao stockDao) { 27 this.stockDao = stockDao; 28 } 29 }

查看数据库：添加成功！
